STOVE.

Specification of Letters Iatent. v Patented Nov, 23, 1909,

Application filed J une 26, 1908. Serial No. 440,688.

To all whom it may concern:

Be it known that we, JOHN M. JOHNSON and GUY W. NOBLE citizens of the United States, residing at li'ielleville, in the county of Republic and State of Kansas, have invented a new and useful Stove, of which the following is a specification.

The invention relates to improvements in stoves.

The object of the present invention is to improve the construction of stoves, and to provide a simple and comparatively inexpensive one, designed for burning crude oil, and adapted to afford a uniform heat with great economy.

A further object of the invention is to provide a clean odorless crudepil burning stove of this character, in which the soot will be intercepted before it reaches the smoke pipe, and from which the soot may be easily removed.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompany ng drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construct-ion, within the scope of the claims, may beresorted to w thout departing from the spirit or sacrificing any of the advantages of the invention.

In. the drawings :F igure 1 is an elevation of a crude oil burning stove, constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a vertical sectional view, taken at right angles to Fig. 2. Fig. 4 is a plan view of the stove, the cap being removed. Fig. 5 is a horizontal sectional view, taken substantially on the line 5-5 of Fig. 3. Fig. 6 is a vertical sectional view, illustrating a modification of the invention.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

The stove comprises in its construction an outer cylindrical shell 1, a bottom 2, a top 3, and an inner cylindrical shell 4, depending from the top of the stove and adapted'to spread and throw the flame outward for causing the same to impinge against the outer shell or casing of the stove, and capable also of intercepting and collecting the soot to prevent the latter from fouling the it has an annular groove or de ression 7,.

surrounding the central taper portion. The annular oove or depression is approximately semi-circular in cross section, and the central tapered portion acts as a spreader and --is adapted to distribute the crude oil uniformly to the different portions of the bottom of the stove. The central tapered or conical portion is formed by the annular groove or depression, and the outer walls of the same extend lipwardly to a point slightly above the a ex 0 the central portion. The bottom 2 o the stove fits within and is secured by screws 8, or other suitable fastening devices to the lower end of the outer shell or casing 1, an air tight joint being provided. The outer shell forms a combustion chamber and the stove is preferably supported by legs 9, which are secured by screws 10, or other suitable fastening devices to the side faces of the bottom at points below the lower end of the outer shell or casing. The lower portion of the bottom is enlarged to extend'beyond the outer shell or casing, which rests upon such extension or enlargement 11. The base of the stove is also preferably equipped with a ring 12, connected by design of pl .in or ornamental trimmings maydbe employed, as will be readily under stoo The top of the stove is provided with in-' ner and outer depending annular flanges 14 and 15, to which are secured by screws, or other suitable fastening devices, the upper ends of the inner and outer shells or casings, air ti ht joints being also provided at the top oY the stove. The inner shell or cas' 4, which is concentric with the outer shell or casing depends from the top and terminates short of the bottom or burner, and the dis tance between the lower end of the shell or casin and the bottom or burner of the stove may %e varied with the size of the latter. The crude oil is ignited upon the bottom or burner of the stove, and the flames passing upward impinge against the outer shell or casing and a uniform heat is thereby secured The stove is equipped with a vertical arms 13 with the legs 9, but any draft pipe 16, piercin the top ofthe stove and havln an upper threaded end 17, which is screwed into a threaded opening of the top 3. The draft pipe is provided wlth horizontal branches 18, spanning the combustion chamber of the stove and piercing the inner and outer shells and having their outer ends secured in Openings in the outer shell and connected at their 1nner ends with the vertical pipe 16 b a suitable coupling 19. A three-way dra t connections is thus provided, and the vertical pipe is preferably made in upper and lower sections, as shown, but any other construction ma be employed, as Will be readily understoo The draft is controlled by top and side dampers 20 and 21, slidably arranged in suitable guides and adapted to regulate the draft by varyin the size of the exposed portions of the en s of the draft pipe.

The fuel may be supplied to the stove in a variety of ways. In Figs. 1 to 5 inclusive of the drawings, a feed pipe 22 is connected with the bottom 2 of the stome, which is provided with a central perforation 23, forming a passage for the oil, which may be forced into the stove by either air pressure or gravity. The feed pipe is provided with an upwardly extending branch or portion 24, which is screwed into an enlargement of the lower portion of the passage 23. The feed pipe is also equipped with a valve 25 for controlling the flow of fuel.

In Fig. 6 of the drawings the feed pipe 26 extends through the vertical draft pipe and terminates at a point above the center of the bottom of the stove. The feed pipe 26 is equipped with a suitable valve 27, and the bottom 28 of the stove is imperforate. The feed pipe may, however, pierce the side of the stove, and the crude oil may be piped from the exterior of a building if desired.

In starting the stove a piece of lighted paper is placed-upon the bottom and the crude oil is fed into the stove and is ignited by the flame of the burning paper. As soon as the crude oil is lighted, the continued feed of fuel will maintain a constant blaze within the stove and the degree of heat may be controlled by varying the flow of the oil.

The stove is equipped at the front with a hinged door 29, havin a transparent portion of isinglass, or ot er suitable material and adapted to afford access to the burner of the stove. The stove pipe is connected with a suitable collar or flange 30, surrounding an opening communicating with the space between the inner and outer shells and preferably located at the back of the stove. Any

soot accumulating within the stove may be conveniently removed through covered clean-out openings 31. The clean-out openings are formed 1n the top of the stove and are located over the space inclosed by the inner shell or casing, and the covers 32 for the clean-out openings may be slidably mounted in ways, or constructed in any other preferred manner.

The stove is designed to be equipped with a plain or ornamental cap 33 of any preferred design, removably arranged u on the top of the stove. The cap is remove to afford access to the clean-out openings and the damper for controlling the draft through the vertical draft pipe.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is

A stove of the class described including a bottom constituting a burner,- an outer shell secured to the said bottom and forming a combustion chamber, a stove top to which the outer shell is secured, an inner shell secured to and depending from the top of the stove and spaced from the outer shell and terminating short of the said bottom, a vertical draft pipe located within the inner shell and communicating at its upper end with the outside air and rovided at a point intermediate of its en s with horizontal branch pipes piercing the inner and outer shells and spanning the combustion chamber, and a smoke pipe connected with the stove at the top of the intervening space between the inner and outer shells.
